will my 87 2.2 turbo block take a 89 2.2 t2 crank?
i have a really good deal on a 89 t2 crank micro polished and turned... i want the round tooth crank for my hybrid build

I 'think' you can but you would be required to use a CB oil pan and seal retainer at the minimum as the seal size and location is totally different between the two.
I can't remember which crank used the bigger seal right now, but I know that one of them you can have the seal surface turned down to accept the smaller seal. To go the other way around you can either do some fab work to graft int he correct seal retainer, or you can drill and tap the block to accept the seal retainer you need and use the correct oil pan.
Its not that simple... The 'depth' location of the seal is totally different between the two. Not sure how much effort the OP wants to invest in making the conversion, but unless theres something extremely special about using an 87 block. I'd get a CB and not have to deal with a bunch of BS thats gonna cost more time and $$$ doing such a swap.
I would go find yourself either a tall deck block or CB. The machining shop charges will far outweigh the cost of buying a CB core. Totally agree with Craig here, not worth the effort. There is a member on this forum that did the opposite. Put a very unique early crank in a CB. Invoice from machine shop was very high. Also took a long time to do.

check with J&H Ryan up there for a common block. Stronger block, and you can get 4 bolt mains.
if i can find a 2.2 CB im all for it!
I've got a 2.2 NA CB in my stash. It just needs the turbo drain back drilled and it's a turbo block. Shipping would be a PITA, though.

I had a crank machined to fit in the opposite block on the seal surface. Now, this was back in 2000 and I've yet to put the engine together, but I did test fit the seal retainer and the crank int he block...it worked in that respect. *shrug*
thats the thing d3nt, its called a common block because the block can handle a 2.2 or a 2.5 crank. so you can get ANY block from 89 to 94 and you should be able to put your 2.2 cb crank in it and for a hybrid build, i would go with a common block anyways...
I would stick with a CB due to the cam gears being easier to make work but I believe someone did it, I did have it bookmarked but with all the changes, need to search again, it was alot of work.
